I believe the most crucial feature of OmniPeek search is the ability to sniff packets based on channel switching.
OmniPeek offers valuable features like a voice bot for service quality checks, expert troubleshooting views, and custom packet color-coding, enhancing application visibility across networks. It excels with connection insights and channel-switching packet sniffing. However, automation, filter configuration, and saving features need improvement, and there are limitations in open environments. Users find the APIs challenging and miss Linux or Unix support, leading some to prefer Wireshark.
